Agree with others. Three thumbs down.
You can always tell an app is going to fail when the grammar in the instructions is poor. I suspect the grammar in the source code is equally poor. I too bought it mistaking it for the free DJI proprietary version. I can’t write a review since I can’t get it to “register” on first running it, no matter how long I wait as the instructions suggest. My guess is that it’s trying to access some files from the official app and DJI quickly caught on and put a stop to it. Good try newbie software writing punks. May all your future drone flights end in horrific crashes!
